[XeTeX] misplaced accents in printout only?

[Arthur Reutenauer]

  Answering for Dominik, as that is easy to check by inspecting the PDF
file (the original one, obviously):

> I assume you have already considered: are the fonts embedded in the PDF?

  Yes.

  Irrelevant, but you're right, it's the first option.

  Possible in general, but that's not what happened here.  The
problematic characters are coded in the PDF as single glyphs.
